I use it myself, so I also have to like it too :)
Amazing software, very easy to use and reliable ! I use it for many years with dual hard drives It's very light, give a second life to old desktops. More plug-ins would be amazing (sockso, new Dynamic DNS services, ...) Thaks !
Great NAS software, small power efficient OS run from a USB stick.
